The withdrawal agreement provides for a transitional period until 31 December 2020, during which time the UK will remain in the internal market, to ensure the smooth flow of trade until a long-term relationship is concluded. If no agreement is reached by then, the UK will leave the single market without a trade deal on 1 January 2021. The withdrawal agreement is closely linked to a non-binding political declaration on future relations between the EU and the UK. The agreement defines the goods, services and processes associated with them. Any provision of goods or services legally put on the market before leaving the EU may be made available to consumers in the UK or in the EU Member States (Article 40-41). The withdrawal agreement also contains provisions for the United Kingdom to leave the Convention setting the status of European schools, with the United Kingdom bound by the Convention and accompanying regulations on accredited European schools until the end of the last academic year of the transition period, i.e. at the end of the spring semester 2020-2021.  Neither the agreement nor the political statement refers to the future relationship in law selection, judicial decision, judicial jurisdiction, recognition and enforcement of judgments. The UK has already hinted that it hopes to agree on a large-scale agreement, broadly in line with the current position.
On 6 September 2020, the Financial Times reported that the UK government was considering drafting new laws to circumvent the protocol of the Northern Ireland Withdrawal Agreement.  The new law would give ministers the power to determine which state aid should be notified to the EU and to define which products at risk of being transferred from Northern Ireland to Ireland (the withdrawal agreement stipulates that in the absence of a reciprocal agreement, all products are considered vulnerable).  The government defended this approach and stated that the legislation was in accordance with protocol and that it had only « clarified » the volumity in the protocol.  Ursula von der Leyen warned Johnson not to violate international law and said that the implementation of the withdrawal agreement by Britain was a « precondition for any future partnership ».  On 8 September, the Minister of Foreign Affairs for Northern Ireland, Brandon Lewis, told the British Parliament that the government`s internal market bill would « violate international law ». »  The Withdrawal Agreement and the Political Declaration On 17 October 2019, the United Kingdom and the EU agreed to withdraw the United Kingdom from the European Union after several failed attempts to secure the approval of the original agreement by the British Parliament. The agreement includes the revised political declaration and the new withdrawal agreement. Formal negotiations were initiated on the basis of the « mandate for negotiations under Article 50 of the EU TREATY », agreed between EU and UK negotiators, which sets out the structure of the negotiations, dates and priorities for the next rounds of negotiations. The UK government has already implemented the provisions of the agreement. A new EU Settled Worker has been fully operational since March 2019 and its provisions are more generous than the terms of the agreement. What is critical is that complainants are not required to provide evidence to confirm their ability in the United Kingdom.
The government has suggested that, even if the agreement is not adopted, it will comply with the provisions on the protection of citizens` rights to the extent that it can do so unilaterally. Therefore, in the case of a non-agreement scenario, EU citizens in the UK should remain able to apply for status in accordance with the terms set out in the agreement. The agreement covers issues such as money, citizens` rights, border agreements and dispute resolution.
